Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Few long-term toxicity tests have been carried out to study the toxicity of tetrachloroethylene to invertebrates of which the outcomes are in the same order of magnitude.

A 28-day NOEC based upon reproduction of 0.51 mg/l is reported for Daphnia magna (Richter et al., 1983). The test concentrations are measured, the test conditions are fully described and so the result is considered as valid. A lower value of 0.45 mg/l is reported for Mysidopsis bahia (USEPA, 1980); no indication is given as to the test conditions and the result is therefore not considered useful for risk assessment. Another study was less critical.
